Hello
We had a cluster of 5 nodes for more than a year and had been working well. We upgraded nodes in the cluster to latest 3.4 one by one and got them back in cluster. Now since last 2 weeks, we have started to see a cluster flapping,
cpg_send_message failed: 9
and see an intermittent disconnect of nodes in the cluster and they come back to normal. But due to this behaviour we face issues with VZDump backup and changes to any VM configurations. We checked the network switches, all are working fine, and supporting multicast traffic.
any suggestions to check this issue would help us resolve this problem.
